vfio-pci-bind VS Complete-Single-GPU-Passthrough

That's exactly what I do. I use this way and works perfectly. https://github.com/andre-richter/vfio-pci-bind

Before booting the VM, I bind the card to vfio_pci using andre-richter/vfio-pci-bind.

I just have unbinding/binding vfio a shot and it works perfectly. I used the script from here https://github.com/andre-richter/vfio-pci-bind

I was trying to get single GPU passthrough to work on my RX 6700xt and Ryzen 5 5600 however after following this guidehttps://github.com/QaidVoid/Complete-Single-GPU-Passthrough I can no longer even launch any VMs or create any new ones. I get this error.

Im assuming you're on a single gpu setup and, as such are trying to do single gpu passthrough with a single nvidia card. so you'll likely have to run some libvirt hooks or smth to run scripts to unbind your gpu once you start your vm. In which case id suggest going through these two guides 1 2 which go over completely passing through your single gpu when you start your vm

Thanks for reply. I didn't find the issue, but I decided to install endeaveour just to not reinstall arch every hour and using this guide I managed to make it work. I guess on bare bones system I missed something every time I tried, but I'm not experienced enough to know what I didn't do to run it.

I have a similar use case. I good good guide to follow would be this but I also have my iGPU disabled completely.

not an expert on this, but you can use the single gpu passthrough scripts to unload/reload drivers for host/vm needs. (no reboots) ssh into the desktop pc and test out what works for you. https://github.com/QaidVoid/Complete-Single-GPU-Passthrough what helped me here was unbinding/binding the vtconsoles before unloading/loading drivers again via tty. If you do it directly on the machine, you may lose tty/framebuffer, which is why I suggested ssh.

I used this and it worked. https://github.com/QaidVoid/Complete-Single-GPU-Passthrough

Hello. I have an RX 6600, and I wanted to use single gpu pass through. I followed this guide. Everything worked fine, until I got to installing the drivers. Once they got installed I got a black screen. I know it installed successfully because I used teamviewer to look at my screen from a different PC. Any help would be appreciated.
